我尝试在angularjs中创建服务,但我一直在获得angular.js:10467错误:[ng:areq]参数'MainController'不是函数,未定义.

HTML:

<div ng-controller="MainController">

<form name="searchUser" method="post">
    <input ng-model="username" type="search" placeholder="Find"/>
    <input type="submit" value="Search" ng-click="search(username)" />
</form>
You are searching for:  {{username}}


<hr />
    <div ng-repeat="(key,value) in data">

        {{ key + " :  " + value}}
    </div>



</div>

<script src="lib/angular/angular.js"></script>
<script src="js/app.js"></script>
<script src="services/Screamer.js"></script>

我的app.js:

angular.module('NoteTaker', []);  // dependcies in array.


angular.module('NoteTaker', []).controller('MainController', function(screamer, $log, $http, $scope, $interval){
    $http({
        method : 'GET',
        url: 'https://api.github.com/users/' + $scope.username
    }).then(function(response){
        console.log(response);
        $scope.data = response.data;
    }, function(response){
        console.log(response);
    });

我在service.js的服务

(function() {
    'use strict'; …

我试图在模板之外声明一个成员函数 - GetValue.

我收到错误:main.cpp | 16 |错误:重新定义'GenericType Test :: GetValue()'| |错误:'GenericType Test :: GetValue()'先前在这里声明|

#include <iostream>

template <class GenericType>
class Test {
public:
        GenericType x;
        Test(){        }

        Test(int y) : x(  y){ }

        GenericType GetValue(){}
};


template <class GenericType>
GenericType Test<GenericType>::GetValue(){
    return x;

}

int main()
{

    Test<int> y(5);
    std::cout << y.GetValue();
    return 0;
}

我的静态topStock方法有什么问题？它引用了股票和股票t.它不应该返回s或t的副本吗？

错误:'.'之前的预期primary-expression 令牌|

#include <iostream>

using namespace std;

class Stock {

public:

    Stock() : x(0){ }
    Stock(int val) : x(val){}

    void display() const;

    static Stock topStock(const Stock& s, const Stock& t) {
     if (s.x > t.x)
        return s;
    else
        return t;
    }

    int x;
};

void Stock::display() const
{

    std::cout << this->x;

}


int main()
{
    Stock s(9);
    Stock y(8);
    Stock z = Stock.topStock(s, y);
    return 0;
}

Samurai依赖于ninja.chirp,但我删除了对ninja.chirp的引用.为什么这段代码继续有效？

    var ninja = {
        chirp: function (n) {
            return n > 1 ? this.chirp(n - 1) + '-chirp' : 'chirp'; 
        }
    };

    function chirp(n) {
        return n > 1 ? chirp(n-1) + '-chirp' : 'chirp'; 
    }

    var samurai = {
        chirp: ninja.chirp
    };

    ninja = {};
    try {
        console.log(samurai.chirp(3));
    }
    catch (e) {
        console.log("no can do.");
    }
</script>

我无法弄清楚为什么我的lambda错了.它应该创建一个make-exp.

(define (exp b n)
    (if (n = 0) 
        1
        (* b (exp b (- n 1)))))

(define make-exp (lambda(n) (lambda(b)(exp b n ))))

(define square (make-exp 2))

(square 3)

错误:2不是函数[square,exp,(anon)]

我需要帮助试图弄清楚为什么我的指针数组不起作用.我正在递增指针地址和I.我的控制台窗口只是挂起.

int *arr = new int[10];
int i = 0;

while (i < 10){
    *arr = i;  // assign the value of arr to i
    arr++;     // increment the pointer by 1
    i++;       // increment i
}

delete[] arr;
